python代码可以自己扩充图像数据集。 无论我们喜欢Keras还是Pytorch,我们都可以使用丰富的资料库来有效地增广我们的图像。但是如果遇到特殊情况: 我们的数据集结构复杂(例如3个输入图像和1-2个分段输出)。 我们需要完全的自由和透明度。 我们希望进行这些库未提供的扩充方法。 对于这些情况以及其他特殊情况,我们必须能够掌...
isalpha() True >>> full_name = 'Parry Wang' >>> full_name.isalpha() False >>> age = '33' >>> age.isalpha() False 注意,isalpha()很严格,只要字符串内容里出现了哪怕一个非英文字母内容,那么isalpha()就会返回False,比如'Parry Wang'(包含了空格), 'Parry_Wang'(包含了下划线)等等。
